Abstract

Aspects of the subject matter described herein relate to updating and validating documents secured cryptographically. In aspects, documents are encrypted to protect them from unauthorized access. An entity having write access to a document may create a new version of the document and sign the new version with a private key. Other entities may validate that the new version of the document was created by an authorized entity by using a public key available in security data associated with the version. The entities that are authorized to create a new version may change which security principals are allowed to create subsequent versions.
